Procedure

Trimethylsilyl cyanide (0.69 g, 7 mmol) was added dropwise to a mixture of 4-aminophenylacetic acid (0.755 g, 5 mmol) and cyclobutanone (0.49 g, 7 mmol) in dioxane (20 ml). The mixture was stirred for 8 hours at 80° C. The mixture was concentrated and chromatographed (dichloromethane:acetone, 60:40) to yield [4-(1-cyanocyclobutylamino)phenyl]acetic acid (46a) (1.138 g, 4.95 mmol, 99%) as a white solid.
